SUMMARY:Topological Phase Transitions: From Duality Web to Symmetric Mass G
	eneration
DESCRIPTION:Featuring Yi-Zhuang You\, Harvard University\n\nPart of the Con
	densed Matter Theory Seminar Series.\n\nTopological phases of matter is an 
	active research area of condensed matter physics. Among various topics\, th
	e symmetry protected topological (SPT) phases\, which are generalizations o
	f topological insulators\, have attracted enormous theoretical interest in 
	the last few year. Much progress has been made in classifying and character
	izing SPT phases. Yet another interesting topic is to study the phase trans
	itions between different SPT phases. In this talk\, I will present a lattic
	e model for (2+1)D bosonic SPT phases\, which is free of the sign problem a
	nd can be explored by quantum Monte Carlo simulations. It turns out that th
	e model demonstrates a rich phase diagram with exotic topological quantum p
	hase transitions. In particular\, I will focus on two of these transitions 
	and report our on-going progress to understand them both theoretically and 
	numerically.
